Threats & Synergies
Rammus
While Rhaast is good against tanks, Rammus is on a level of his own. With the increase armor given as well as an AOE ult that still damages you in Umbral Trespass, Rammus isn't a champion to take on alone.
Leona
Leona's ult could keep the enemy team in one place. This being said, using either form's Blade's Reach will help in your teams engage. Her stuns allow the some for individual foes.

Champion Build Guide
Base Kayn
Passive: The Darkin Scyhte: As Kayn damages enemy champions, he builds up points that will allow him to transform into one of two forms: Shadow Assassin (Blue) or Rhaast (Red). To become Shadow Assassin, attacking ranged champions will help you achieve this form. To become Rhaast, melee champions are the way to go.
Q- Reaping Slash: Kayn dashes a short distance, then spins his blade at the end of the dash.
W- Blade's Reach: Kayn raises his blade and drops it down in a straight line. Enemies damaged by Blade's Reach are slowed.
E- Shadow Step: Kayn can travel through walls and structures, gains movement speed, and heals for a percent of his attack damage.
R- Umbral Trespass: Kayn can travel into an enemy he recently damage. Once an enemy is selected, Kayn can either wait four seconds or reactivate his ultimate to leave and do damage to his opponent.
Shadow Assassin
Passive- The Darkin Scythe, Kayn: Kayn deals bonus magic damage for the first four seconds in combat. This ability is put on an eight second cooldown after.
Q- Reaping Slash: Kayn dashes a short distance, then spins his blade at the end of the dash.
W- Blade's Reach: Blade's Reach range is increased and allows you to move while casting it.
E- Shadow Step: Shadow Step now prevents Kayn from being effected by slow abilites, gains additional movement speed, and has a reduced cooldown.
R- Umbral Trespass: Range for Umbral Trespass is increased and resets the cooldown on Kayn's passive.
Rhaast
Passive- The Darkin Scythe, Rhaast: Rhaast heals for a percentage of damage dealt to enemies.
Q- Reaping Slash: Rhaast dashes forward and spins his blade at the end, dealing a percentage of the enemies health as damage.
W- Blade's Reach: Rhaast raises his scythe and drops it to damage and knock-up enemies it hits.
E- Shadow Step: Able to move through walls and structures, healing you for a percentage of your attack damage.
R- Umbral Trespass: Rhaast goes into an enemy he recently damaged. After four seconds or reactivating his ult, he deals and heals for a percentage of the target's maximum health.
Q: How will I know what runes to take?
A: Examine the enemy team during champ select. An easy indicator in deciding forms is this: does the enemy team have at least two tanks? Does my team lack a tank? If the answer is yes to at least one of these questions, then it is best to go Rhaast. Otherwise, go Shadow Assassin.
Q: Can I switch forms in the middle of game?
A: No. Once you select a form to transform into, you are stuck like that for the rest of the game. However, if you are uncertain, you can stay base Kayn for as long as you like until you decided what would be best.
Q: What if their team has a balance between squishies and tanks?
A: If it is balanced between the two, it is better to go Rhaast since you have to deal with tanks still. Kayn will do damage, but Rhaast will ensure kills on tanks.
Q: Why not switch builds to build tank on Kayn and damage on Rhaast?
A: Each build is designed specifically for each form. You can swap builds, but to get better use, it is best to stay with a build at least similar to what is stated above.
Q: What happens if I'm behind because I have to gank often?
A: Take a few minions from the lanes you gank. Every second away from jungle is taking experience and gold, so tax a bit after ganking a lane.
Sunfire Cape: A basic item that is useful. While using your ult, Sunfire Cape still works, damaging the enemy while you remain inside them.
Thornmail: Another basic item. It's useful for, well, basic attacks from your enemy. Works well against a fed ADC or fed Nasus.
Adaptive Helm: If against a champion like Teemo, Heimerdinger or Brand, Adaptive Helm helps lessen the damage you may take from them while in combat.
Zz'Rot Portal: It gives a balance between armor and MR, and if you are backdooring, helps with that.
Death's Dance: Q will give a healing bonus for damage done, so stacks well with Kayn's passive.
Youmuu's Blade: Gives bonus movement speed to chase enemies as well as give lethality to add to the finishing blow.
Last Whisper: Good ol' reliable if there is a tank that is giving you too much trouble. Upgrade Last Whisper into whichever weapon, depending on the target.
Edge of Night:Banshee Veil for AD, this is useful if their team has a lot of CC and Mercurial doesn't seem to cut it. Also, in my opinion, this is much better than Mercurial since you can protect yourself rather than having to be attacked by a spell, taking damage, then using the Mercurial.
